(Not mentioning BoF's pics again, as am v )
DH and I started going out at school, we were part of same large 'gang' of mates, so every day we saw each other and most evenings were all out together but were both 17 so went home to our own beds.
Then he moved to uni, 250 miles away, then I moved to uni, first the other end of the country, then the other side of europe for a year seeing each other as often as we could, normally monthly.
Then we moved in together and 13 years later are here with 2 dd's. Sort of schoolkid intense mixed with slow burn then.
It worked as I would say he is my best friend. Even girls I was at school with aren't my mates as mmuch as DH is now.
